So lets see force is measured in what? And pressure is measured in what? USA stuff only not other units.

pressure
the continuous physical force exerted on or against an object by something
force
strength or energy as an attribute of physical action or movement

So according to the definitions the best one is pressure, since when measuring the spring, that is the definition that best applies.
So SPRING PRESSURE is the winner.

It is only FORCE when the engine is running.

What a load of bollocks.

Force is measured in pounds or newtons.
Pressure is force per unit area so pounds per square inch or newtons per square centimetre.

All my stuff is from dictionary. Maybe you should volunteer to rewrite them.
The definition says what it is. Not how or what ever the certain units of measure you wish to use to do so. Simple stuff, not rocket science.
So yeah its like bollocks to even post that.

Definition[edit]
Pressure is the amount of force applied perpendicular to the surface of an object per unit area.

On the subject of proper nomenclature, the "oversize " bearings thing seem to be catching on.

I guess that's what happens when kids get access to computers. Or maybe it's just people with Engrish as their third language?
